CSPEC is used in a wide variety of scientific applications, spanning the life sciences, functional materials and chemistry. Its key capability is to follow kinetic events in situ or in operando, enabled by very high flux. It will probe the structures, dynamics, and functionality of large hierarchical systems as they change or operate. Hierarchical systems include liquids, colloids, polymers, foams, gels, and granular and biological materials as well as the ever complex low-energy dynamics of energy materials and emergent magnetic behaviour. As we probe the dynamics of these systems, we unlock the principles that steer the organization of atoms into complex matter, and we can develop and improve functional materials for solving societal challenges.
